Plaquemines LNG Terminal power station is a 2,860 MW gas power station in Louisiana, United States of America. It is operated by Plaquemines Expansion LLC. Based on its capacity (estimated), it can supply roughly 3.2 million homes (estimated). It ranks #56 of 10,938 United States of America power plants by installed capacity. Commissioned in 2024, it is around 2 years old — recently built. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
The public capacity above is the current source-record value. A 2026 tracker candidate lists 720 MW for Plaquemines LNG Terminal power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

At 2,860 MW, Plaquemines LNG Terminal power station is well above the median gas plant in United States of America (121.2 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Baker Hughes (Aero). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 29.6°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
